I ROBERT S. HICKISH, OF TUCKAHOE, NEW YORK, ASSIGNOR, BY MESNEASSIGNMENTS, f l TO EDWARD T. POWELL, OF COLUMBUS, OHIO.

FIRE-EXTINGUISHER.

Be it known that I, lolnnrr S. Hiciirsn,

, a-:eitizen of the United States, and a resito insure a steady supply of this liquid to 14,-'at one end of the cylinder, and 'fitted the pump,l irrespective ot' the position in i 'which the device is placed, as the same is thrown about to direct the sprayfotf liquid iat different elevations or to different points.

With this end in ,view my invention resides in a certain special device of a con- .struction and combinations of parts which will 'be fully set out nereinatter, and pai ticularly pointed outin the claims.

Reference is now had to the' accompanying drawings, which illustrate as an example the preferred embodiment ot my invention. In said drawings Figure l is a longitudinal section; Fig. 2 is a cross section; Fig. 3 is a longitudinal section of a modilication. Referring first to Figs. .1 and 2, 1() indi- Cates the harrel or cylinder ot the pump, the saine. being fitted with a piston 11., the rod, l2, whereof passes through a stldiing-box,

outside of saidstuling-hox with a handle, :15. At the end of the cylinder I()7 opposite the Stutling-hox 15, a pet cock 1G' is located through which the flood is ejected.

Said cylinder or barrel 10 is seated or otherwise ffirnily secured within the upper end ofthe tank 17. r1`he preferred 't'orm oi this tank is trian, ,ular7 as shown in Fig. 1, and {lattened in cross section, as shown in Fig. 2. This is the most favored form tor .the tank, and hy heing flattened as shown, it will hang snugly against a wall or like support. for which purpose the tank is'furnished with a bail 1.8 (see Fig. Z). For convenience in Handling, the tank is also provided with a. handle 19 by which the whole apparatus may loe carried, and also by which the hand ofthe operator may be steadied in gripping Specification of Letters Patent.

the tank while operating the pump. The connection hetween the pump, cylinder and tank at the rear end ot' the latter is, of course, hermetic. The pump is double-acting` and is 'l"urnishcd.v according to this. with two inlet or intake pipes 20, which extend from the pointed lower extremity ol' the tank 17 upward through the tank to the respective end portions of the cylinder 10. .\t the said upper ends oi' the intake, tuhes 12() check valves 2l arc provided. the same seated outwar'd from the cylinder to prevent hack low through the. intake pipes. Near the discharge end ot the c vlindcr is located a4 plug or partition 2'.) ilted with a check valve 2?). (he saine opening toward thepet cock lti.

)l isa h v-pass pipe extending l'rom the end of thcc \'lindcr l2 adjacent the stalling-hgxvll tothe opposite end ot' the cylinder, hut at a point helween the plug 22 and the pct cock 1V. 'l`his h v-pass pipe 2l is intended -to cariv the liqllid from the right hand or rear 'i end ol' the cylinder around to the front end and its discharge end` said hy-pass 24 heiligv Jfurnished with a check valve 25 opening into the discharge end oi the cylinder li).

'l`he tank 17 is furnished with a plug 2G which is preferahtv screwed into placet and therefore heilig easily removahle.y and this plug carries a vent valve '2T vieldingly seated hy a spring 2H. Said valve is designed to open inward under the influence oi theat mospheric pressure to. allow the easy discharge oi' the contents of the tank.

ln the operation of thev device the tank 17 .is filled with the iuid lire extinguishing sul)- stance7 and normally the. pet cock 10 is closed. The tank is lilled through the opening and is normally closed hythe plug 26. Then it is desired to discharge the whole or a part ol' the contents ot the device upon a ire-T the pct cock 1.('5 is opened and the punlp piston is reciprocatcd in the cylinder. Referring to Fig. 1, and assuniing that the piston is moving rightwardly,the valve 2l.

ot' the right-hand intake. pipe. 2() will` he ing the nu'ivement oi' the. piston, the contents ot' the cylinder thus introduced are ejected, the said left-hand valve :l seating and the valve 23 unseating to allow the free passage of the liquid. 'llu` letlvir/i move-ment of BEST AVAILABLE COF" the pistou just described will lill the rightliandend oi' the c vlinder 10. and upon a second rightward movement ot' the piston, the valve will unseat, and the liquid in the right-hand end ot' the piston will be ejected from the b v-pass pipe 2l and out into the atmosphere,through the cock 1G.

The form of the tank, as I have before stated, is not essentiahthough I prefer the triangular forni illustrated.

Fig. 3 illustrates` the tank 1T of rectangu lar torni. Various other shapes may be given to the tank without departing from the spirit ot' my invention. l

Fig. 3 illustrates a further modiication of my invention wherein one iiitaketube '20 is provided. This tube is liexible and furnished with a weight 29. This weight will 4cause the intake tube to swing from side to side as the deviceis tilted. and will always hold the receiving end of the intake tube in the lowest part of the tank, insuring that all of the contents of the tank are subject to the sucking action of the pump. Otherwise the forni of the invention shown in Fig. 3 is the same as that previously described.

Having thus described my invention, what I claim is:

I. A fire extinguisher comprising a triangular tank in combination with a liquid pump extending across one of the sides of said triangular tank and rigidhy secured thereto, said pump provided with an intake tube permanently extending to the angle of the triangular tank which is removed from the pump. l

A fire extinguisher comprising a triangular tank in combination with a double acting liquid pump extending across and constituting one of the sides of the said tank, said pump being rigidly secured to said side `and provided with two intake tubes extending from the respective ends otsaid pump to the angle of the triangular tank remote from the pump.

3. A fire extinguisher comprising, in combination, a substantially trii'ingular shaped tank fiattened in cross section, a manually operable pump the casing oi which closes one of the sides of said tank, and an intake connected to said pump the free end abt' which is adapted to extend into the angle ot the triangular tank opposite the pump.

bination, a substantially flat triangular tank and a double acting liquid pump the casing of which closes one of the sides of said tank, and intakes ,secured to said pump and the free ends of which are adapted to extend into the angle at the' lower portion `ofy the tank.

5. In a fire extinguisher, a substantially triangular shaped tank flattened in cross section, in combination with a manually-operable pump the casing of which closes one ot' the sides of the said tank, said pump coinprising a reciprocating piston, Huid intakes charge ports for said pump, and check valvesA in said intakes and discharge ports.

T. -l lire extinguisher comprising a triangular tank iii combination with a pump extending across and constituting one of the sides of the said tank. said pump being rigidlv secured to said side and provided with inlet and discharge tubes one'of which extends into the angle of the triangular tank opposite said pump.

S. In a fire extinguisher, a substantially triangular shaped tank flattened in cross section, in combination with a manuall)v operable pump the casing of which closes one of the sides of the tank, said pump comprising a reciprocating piston, alluid intake for the pump extending into the angle of the triangular tank opposite said pump, and a plug located in the forward end of the pump barrel and provided with a discharge port therein.

f). In a lirevextinguisher, a substantially triangular shaped tank flattened in cross-section, iii combination with a inanuall)1 op erable pump the casingof which closes one of the sides of the tank, said pump comprising a reciprocating pistoii,fhiid intakes connected to the chambers `in the frontaiid in the rear ofvsaid piston and extending into the angle of the tank opposite to the pump. discharge means provided with ducts which discharge into"a common chamber at the forward end of said pump,and a discharge noz.-

- '/.le connected to the last mentioned` chamber. l. A fire extinguisher comprising, 1n com-[Q In testimony whereof I have signed my Ynaine to this specification in ktliepresencl` ofitwov subscribing witnesses. ROBERT Si. HICKISH.
